EDWIN L. HARMON, OF GROTON, NEW YORK, ASSIGNOR TO AMERICAN ROAD MACHIN- ERY COMPANY,- INC., OF KENNETT SQUARE, PENNSYLVANIA, A CORPORATION OF DELAWARE.

a citizen of the United States, residing at Groton, county' of Tompkins, and State of New York, have invented a new and useful Improvementin Road-Oilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification. I

My invention relates to vehicular machines, sometimes called road oilers, for distributing bitmuinous and binding material upon roads. The main object of the invention is to provide readily adjustable means for governing the lateral position of the transversely extending row of nozzles through which the material is discharged.

The drawings show preferred embodiments of the invention, in which Figure 1 is a rear view of my improvement. f

Fig. 2 is a plan view of the same;

Fig. 3 is' a side view of the same;

Figs. 4 and 5 are views, similar respectively to Figs. 2 and 3, showing a modification.

, In describing the invention, I shall omit references to more or less necessary parts of the machine that do not intimately cooperate with the parts embodying the inven tion, which relates solely to the pipe construction between the supply tank and the nozzles.

The supply tank a is supported from the vehicle body in any known way. Extending downwardly and rearwardly from the tank is a pipe 6 which, through a pump a, communicates with an upwardly extending pipe at.

Swiveled on the pipe 03 is a rearwardly extending pipe 6, which in turn is swiveled on a downwardly depending pipef secured to the center of a transversely extending distributer pipe 9. The connections between the pipe e and the upright pipes dand f are preferably afforded by means of elbows 70. at opposite ends of the pipe 0 which turn respectively on the axes of the pipes d and f.

The opposite ends of pipe 9 turn downward, the downward extensions It being screwthreaded in nozzles in two transextending alining pipes 2' provided with iseharge nozzles j,

Application filed December 8, 1916. Serial No. 135,751. l

The nozzle pipes 71 extend in a horizontal direction parallel with the axis of the wheels. It is desirable to provide for adjusting these nozzle pipes in a lateral direction so as to bring within range of distribution areas of roadway considerably to one side or the other of the vehicle wheels. The above described construction permits this lateral ad- 'justmentto be effected by a transversebodily movement of the pipe 9. As the pipe f moves with the pipe 9, the rear end of the pipe e is carried along with it, the forward end of pipe 6 swinging on pipe 03 on the latters 'axis. The lateral movement of pipe 9 shortens the distance, measured in a line at right angles to the axis of the vehicle wheels, between pipes d and g, and consequently the two fixed supports and guides m for the pipe 9 are slotted to admit of a bodily rearward movement of the pipe g. As the pipe 9 and the nozzle pipes 01 are adjusted laterally, they may not at all times occupy a position of precise parallelism with 'the axis of the wheels, although they can depart but slightly therefrom; but such exact parallelism is unimportant, it being obvious that in any lateral adjustment of the nozzle pipesthey will maintain-their position of parallellism with the roadway and be guides n for the pipe 9 are not slotted and,

that the pipe 0 (corresponding to pipe 6) has a telescopic connection with the elbow 79 swiveled on pipe f. In this construction the lateral movement of the pipe 9 and the nozzle pipes 2' causes the rear end of pipe 0 to move in the direction of its length within its seat in the elbow p, and the nozzle pipes 11 will at all times maintain a position of exact parallelism with the axis of the wheels.

The guides m or n and the hanger 1" for the pump are suspended from the main frame 8 of the machine. The wheels 15 are shown in: dotted lines.

to go ahea I have referred to the screw-threaded connections between the depending extensions it of the distributer pipes g and the nozzle pipes 2'. Ordinarily this connection is a rigid one, but ifeither'of the nozzle pipes theycan' be madeas a single; pipe if it is caredto assume the risk of 111. ury from striking; obstruction.

Ha vlngnow. fully described myinvention,

tvhat-I desireto claim and protect by LettersiPatient is:

1.111 a machineof the character described; the combination with a transversely movable distrib-uter pipe and extensions at opposite'ends thereof, of two parallel upright pipes,.=one disposed. behind the other,

-whosefizupperendsare;at a common level, a

swinging radius pipe, means including swivelect connections connecting opposite-ends of the radius pipe with the'npjper. ends of the two" upright pipes, a -supply. tank, a pipe connection extendingtheret rom having a rear upturned end; extending toward the front upright pipe, apump interposed between and communicatingwithsaid-a'ear upturned endofi the-tank, pipe and the..lower ends of the front uprightpipe, and. two separate-nozzle-pipes swingable on the axes of, and-secured between their ends to, the respecti-ve'extensions of the distribute]: pipe,

theinne r ends of the two nozzle pipes closely approximating:

2. In a machine of the character described, the combination With a supply tank, of a supply pipe communicating with the supply tank, a transversely movable nozzle pipe structure, guides permitting the latter to move transversely but restraining it'froni moving forwardly or backwardly, a swinging radius pipe located between the supply pipe and the nozzle pipe structure,- and means,ineluding swiveled connections and a telescopic joint, connecting the radius pipe with the supply. pipe and the. nozzle. pipe structure.

3. In amachine of the character described, the combination .with a laterally movable distributer pipe and extensions; at Opposite ends thereof, of a supply tank, a pipe communicating with the supply tank, a swinging: radius. pipe means including swiveled connections connecting opposite ends of. the radius pipe with the'other two pipes, and't-wo separate nozzle pipes,;eaeh

secured between its-ends to one of said ext'ensionsof the distributer. pipe, thetinner ends of the two nozzle pipes closely approximating and t'heouter ends thereoii extending a substantialdistance beyond said extensions, said nozzle pipes beingscrew threaded to said extensions in such direction as to permit the outer end of'either pipe to swing backwardly when encountering. an. ob-

. structiojnbut affording-otherwise a substantially rigid connection .with said extension. In testimony of. wh ch invention", I have hereuntoset my hand, at. Groton, N. Y.,
